Coal Mill Energy Consumption Iron Ore Distribution In Africa

The influence of grinding conditions on the production of fine particles and the width of the particle size distribution produced during ball mill grinding was investigated.Licenses for our milling technology can be found in all coal-powered regions of the world. Pulverizing solid fuel to powder enables its drying and transport for combustion in large furnace sizes. Fine grinding increases the fuel exposed surface area while simultaneously drying and controlling its distribution.The circulation grinding Attritor (“Q” machine) is a combination of an Attritor and a large holding tank which is generally about ten times the size of the Attritor. The unique principle of the “Q” Attritor is the high circulating (pumping) rate, which results in a faster grind and a narrower particle size distribution.The effect of the different grinding methods on the mineral distribution within the pulverized coal was investigated by using proximate analysis,.
